NTP is not synchronizing

Hi Guys

I have configuered my devices with the following ntp command

ntp server 10.20.20.21 source GigabitEthernet0/0

but when I check following

sh ntp status

Clock is unsynchronized, stratum 16, no reference clock

nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**18

reference time is 00000000.00000000 (04:00:00.000 AEU Mon Jan 1 1900)

clock offset is 0.0000 msec, root delay is 0.00 msec

root dispersion is 0.00 msec, peer dispersion is 0.00 msec

show ntp association

address ref clock st when poll reach delay offset disp

Time source is NTP

Am I missing some thing why my devices are not synchronizing with NTP time, as I need it badly for my MARS Server.

Re: NTP is not synchronizing

Asfar has posted this same question in the LAN Switching and Routing forum where there is active discussion ongoing. I suggest that any discussion be consolidated in the LAN forum.
